The hospital's director of emergency management said, like Boston, they prepare for mass casualties and disasters with training and readiness drills.

Joshua Frances said that in the post-9/11 world, the communication between state, federal and local officials, as well as health agencies, has increased.

He said that allows all agencies to be on the same page during and after a big event.

"Preparations are really important, and increased communications between the agencies has made Maine a much safer place, and clearly they showed that... Boston was able to handle the influx of patients because of similar preparations," said Frances.

Frances said he has been part of medical teams at the Boston Marathon in the past, and said there were thousands of medical staff already in place when the explosion happened.
